GATE.

SPECIFICATION forming part of Letters Patent No. 560,776, ated May 26,1896.

Application filed April 11, 1895- To all whom it may concern:

Be it known that I, JAMES H. CHRISTOPHER, of Morrisonville, in thecounty of Christian and State of Illinois, have invented certain new anduseful Improvements in Gates; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, reference being had to the accompanying drawings, which form part ofthis specification.

My invention relates to improvements in gates; and the object of thesame is to provide an improved opening and closing mechanism.

A further object is to provide the gate with an improved verticaladjustment.

A further object is to arrange the operating devices for opening andclosing the gate and for controlling its vertical position, so that thesame may be actuated without alighting from the vehicle.

A further object is to provide an improved latch and latch-operatingmechanism.

Still a further object is toprovide an improved device for holding andtwisting the gate-forming wire strands.

With these objects in view my invention consists in the novel featuresof construction hereinafter fully described and claimed, and illustratedin the accompanying drawings, in. which- Figure 1 is a perspective viewof the gate when closed. Fig. .2 is a similar view taken from adifierent point of view with the gate ajar. Fig. 3 is an elevation ofthe verticallyadjustable gate-supporting derrick. Fig. at is a detailview of the wire-twisting head.

A designates the double gate-post, preferably supported upon theground-surface by a block or other device and held from lateraldisplacement by braces A. A lower bearing-block B and upperbearing-block C move vertically in thevdouble post,the same beingconnected by rod C. The upper block is pro-. vided upon its outer endwith the frictionrollers Z) and upon its inner end with the cross-pin b,which bears on the inner side of the post, while block 13 has thefrictionrollers 0 upon its inner side and the cross-pin 0 bearingagainst the outer side of the post,

the said cross-pin being secured between the ends of an arm D, whichlatter is pivoted at its inner end to the upper surface of block 13,while at its outer end it is provided with the vertically-disposedsheaves D. The outer portion of the said pivoted arm is confined toblock B by stapled. The gate-supporting mechanism is carried by blocks13 and C, and the latter, besides forming bearings for the gate-support,secure to the same vertical adjustment through the medium of chain E,having its ends secured to the inner ends of levers E, fulcrumed betweentheir ends to braces A and at their outer ends extending throughguide-posts F, as shown. Said posts are provided with removable pins f,which are insertible through the post and lever, so as to hold the outerend of the latter in a raised position, while each post is also providedwith a pivoted latch f for locking the lever down with its forward endin a raised position, as indicated in Fig. 2.

-For supporting the gate G, I pivot between bearing-blocks B and C thederrick-post II, provided with the extended cross-arm H, to which thegate G is pivotally secured between its ends, as indicated at G. Arms IIare braced to post H by the twisted wire 72-. A bracket I, which iscurved forward at its extremities, is secured horizontally to post IIand provided with the pivoted cross-arms I, which latter at their freeends are connected by lines '5 to the ends of operating-levers J,loosely secured between their endsto postsF. Theopposite ends of saidlevers J are connected directly together by the line J. Arms :1 areconnected between their ends to the free ends of the vertically-swingingarm K, as shown, and the said arm is connected be tween its ends bylineK to latch L. Said latch is pivoted at its outer end to one of thederrick cross-arms II and at its free end is extended through a recessin post II and held normally in a depressed position by the coiled 9 5 Ipivotally connect thereto at a point midway between the center and rearend of the gate the arm M, pivotally secured at its rear end on verticalbolt M, supported by post N directly back of main post A, as shown. Bymeans of this arm connection it will be seen and understood that whenthe derrick is turned to one side the gate will have a pivotal movementon arms H thereof and will be caused to fold back flatly against thederrick. The gate is pivoted centrally on the derrick and is provided ateach end with a notched catch 0, so that when the gate is closed, as inFig. 1, one of the catches will be engaged by latch L, while when thegate is entirely open the other catch will be in engagement with thelatch. By this arrangement one and the same latch serves to hold thegate both open and closed. The gate, when being operated, having alongitudinal as well as swin ging movement, is readily projected betweenstrips T on the inner side of the outer gatepost T, so that when closedacross the road the free or outer end of the gate is securely held frommovement in either direction, the longitudinal retracting motion securedfrom the operatingmechanismjust described being necessary to remove itfrom between said strips. It will be understood that the operating-linewhen drawn upon for either opening or closing the gate exerts such apullupon the pivoted cross-arms I as to raise pivoted arm K, thuslifting latch L through the medium of line K from engagement with thecatch carried by the gate.

In order that the movement and operation of arm M may be entirelyaccurate, the same is so arranged as to move vertically with the gatewhen the latter is either raised or lowered, and for this reason theouter end of the arm is allowed a vertical movement on the bolt M,before mentioned. In order to support the outer end of the arm when thegate is in a raised position as well as to assist in the elevation ofthe end of said arm, the depending latch Q is provided, which is 0011-nected at its free end to the upwardly-extending weighted chain Q, whichdepends over roller R, while line B extends from the point of connectionof said chain Q to the lower derrick bearing-block, so that when thegate and arm are raised the weighted chain Q will exert an upward pullupon latch Q, and cause it when raised to engage the laterally-extending bracket N 011 post N, while when the gate is lowered lineB will draw the said latch inward and out of engagement from saidbracket, and thus permit the outer end of arm M to descend along withthe gate. An upwardly-extending inturned catch S is secured to the upperedge of the gate and adapted to engage arm M when the gate is closed forthe purpose of bracing together the gate and arm, and thus making thestructure more rigid and secure.

By means of the mechanisms and devices herein shown and described itwill be seen and understood that the gate may be adj usted either upwardor downward in a closed or open position or when partially opened. The

connections are such that the outer end of the long guiding-arm M hasits movement controlled automatically.

The gate G is made up of an outline framework provided with a series ofvertical and transverse wire strands U. Each strand is a doubled wirehaving one end secured to the gate-frame, while the opposite endsurrounds the twisting-head V,havin g an axially-formed bearing at oneend and a wrench hold at its outer projecting end. This twisting-head isslotted longitudinally on opposite sides, around which the wire islooped, so as to secure a firm hold for twisting.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination of a gate-post provided with a guideway, agate-support movable vertically in said guideway, and the loversextended in opposite directions and connected at their adjacent ends tothe support so as to adjust the same, substantially as shown anddescribed.
